[0038] The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0039] It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0040] It will be understood that, although the terms “first,”“second,”“third” etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,”“component,”“region,”“layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

[0041] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”, “an,”“the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. Thus, reference to “an” element in a claim followed by reference to “the” element is inclusive of one element and a plurality of the elements. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.”“Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and / or “comprising,” or “includes” and / or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and / or groups thereof.

[0042] Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

[0043] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0044] Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and / or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

[0045] In an embodiment of the disclosure, an XYZ coordinate system may be used in the drawings as a cartesian coordinate system. For example, a positive Z-axis direction may indicate an upward direction, and a negative Z-axis direction may indicate a downward direction.

[0046] The plane formed by the X-axis and the Y-axis may be a horizontal plane or a plane parallel to the horizontal plane. For example, a positive Y-axis direction may indicate a rearward direction, and a negative Y-axis direction may indicate a forward direction. For example, a negative X-axis direction may indicate a right direction, and a positive X-axis direction may indicate a left direction.

[0091] The metal sheet body 310 may be coupled or fixed to the housing 100 (see FIGS. 3 to 5). The metal sheet body 310 may include or indicate a first metal sheet body 311 or a second metal sheet body 312.

[0092] In an embodiment, for example, the first metal sheet body 311 may be coupled or fixed to the first housing 110 (see FIGS. 3 to 5). In an embodiment, for example, the second metal sheet body 312 may be coupled or fixed to the second housing 120 (see FIGS. 3 to 5).

[0093] The metal sheet core 320 may extend from the first metal sheet body 311 toward the second metal sheet body 312. In an embodiment, for example, the metal sheet core 320 may connect the first metal sheet body 311 to the second metal sheet body 312.

[0095] The metal sheet core 320 may face the hinge module 130 (see FIG. 3). In a state where the housing 100 (see FIGS. 3 to 5) is unfolded or folded, the metal sheet core 320 may be bendable, i.e., straightened (in an unbent state) or bent (in a bend state).

[0096] At least one opening may be defined or formed in the metal sheet core 320. In an embodiment, for example, the metal sheet core 320 may form a lattice pattern. As a result, the metal sheet core 320 may be easily bent or straightened.

[0097] In an embodiment, for example, the metal sheet core 320 may include a core bending portion 321. The core bending portion 321 may be provided with at least one opening or may form a lattice pattern. During a process of straightening or bending the metal sheet core 320, the core bending portion 321 may be straightened or bent.

[0098] In an embodiment, for example, the metal sheet core 320 may include a core extension 322. The core extension 322 may be connected or coupled to the metal sheet body 310.

[0099] The core extension 322 may extend from the core bending portion 321. The core extension 322 may include or indicate a first core extension 3221 or a second core extension 3222.

[0100] In an embodiment, for example, the first core extension 3221 may extend forward from a front end of the core bending portion 321 toward the first metal sheet body 311. In an embodiment, for example, the second core extension 3222 may extend rearward from a rear end of the core bending portion 321 toward the second metal sheet body 312.

[0101] The metal sheet body 310 and the metal sheet core 320 may include or formed of materials different from each other. In an embodiment, for example, rigidity of the metal sheet core 320 may be greater than rigidity of the metal sheet body 310. In an embodiment, for example, a thermal conductivity coefficient of the metal sheet body 310 may be greater than a thermal conductivity coefficient of the metal sheet core 320.

[0102] In an embodiment, for example, the metal sheet core 320 may include or be formed of a material including at least one selected from stainless steel or titanium.

[0103] For example, the metal sheet body 310 may include or be formed of a material including at least one selected from graphite, aluminum, or copper.

[0104] Referring to FIGS. 1 to 8, the processor 12 may be accommodated in one of the first housing 110 and the second housing 120. When the processor 12 operates, heat may be generated in the processor 12.

[0105] When heat is generated in the processor 12, a temperature of the processor 12 may increase. When the temperature of the processor 12 increases, performance of the processor 12 may deteriorate. Therefore, the heat generated in the processor 12 needs to be removed.

[0106] In an embodiment, for example, the processor 12 may be accommodated in the second housing 120 (see FIGS. 3 to 5). In an embodiment, for example, the processor 12 may face the second metal sheet body 312.

[0107] At least a portion of the heat generated in the processor 12 may be transferred to the second metal sheet body 312. At least a portion of the heat transferred to the second metal sheet body 312 may be transferred to the metal sheet core 320.

[0108] A heat transfer coefficient of the metal sheet core 320 may be less than a heat transfer coefficient of the metal sheet body 310. Therefore, a separate heat transfer passage may be desired to be provided to transfer the heat between the second metal sheet body 312 and the first metal sheet body 311.

[0137] The inner protection body 410 may include or be formed of a material including polyethylene terephthalate (PET). In an embodiment, for example, the inner protection body 410 may suppress water from being introduced into the metal sheet layer 300 from the outside, thereby effectively preventing the metal sheet layer 300 from being corroded.

[0138] In an embodiment, for example, the inner protection core 420 may be formed of a material including thermoplastic polyurethane (TPU). In an embodiment, for example, the inner protection core 420 may effectively prevent foreign substances from being introduced into at least one opening or pattern formed in the metal sheet layer 300 from the outside.

[0139] The inner protection layer 400 may include an inner protection heat transfer unit 430. The inner protection heat transfer unit 430 may define or form one surface or two surfaces of the inner protection layer 400.

[0143] In an embodiment, for example, at least a portion of the heat generated in the processor 12 accommodated in the second housing 120 may be transferred to the second metal sheet body 312 and the second inner protection body 412.

[0038] The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.

[0039] It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0040] It will be understood that, although the terms “first,”“second,”“third” etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,”“component,”“region,”“layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

[0041] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”, “an,”“the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. Thus, reference to “an” element in a claim followed by reference to “the” element is inclusive of one element and a plurality of the elements. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.”“Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and / or “comprising,” or “includes” and / or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and / or groups thereof.

[0042] Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

[0043] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0044] Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and / or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

[0045] In an embodiment of the disclosure, an XYZ coordinate system may be used in the drawings as a cartesian coordinate system. For example, a positive Z-axis direction may indicate an upward direction, and a negative Z-axis direction may indicate a downward direction.

[0046] The plane formed by the X-axis and the Y-axis may be a horizontal plane or a plane parallel to the horizontal plane. For example, a positive Y-axis direction may indicate a rearward direction, and a negative Y-axis direction may indicate a forward direction. For example, a negative X-axis direction may indicate a right direction, and a positive X-axis direction may indicate a left direction.

[0047] A display device according to an embodiment can be applied to various electronic devices. An electronic device according to an embodiment includes the display device described above and may further include a module or device having additional functions in addition to the display device.
